Application filed May 1, 1919. Serial No. 293,941.

' To all whom it may concern:

Be it known thatI, CHARLIEQ. Jnmn ns, a citizen of the United States of America,

-.residing at Fort Worth, in the county of Tarrant and State of Texas, have invented certain new and useful Improvements 1n Rotary Engines, of which the following is a.

specification.

My invention relates to gas or gasolene engines and more particularly to rotary engines, and the object is to provide an engine of' such construction that it .will not. be readily heated because of the ready expansion and exhaust of the'gas, to provide sim- 1 ple and novel means for closing the space between the piston 'and'cylinder at all times, and to provide an engine which is simple and economical of construction and eas ly operated. Other objects and advantages will be fully explained in the following description and the invention will be more particularly.pointed out in the claims.

Reference is had to the accompanying drawings whichform apart of this application.

, a F igurel is an interior elevation of the engine, partly in section, one side of the-casing cylinder being removed. Fi 2 is a diametrical section of the engine cy in'c'ler and also of the ignition chamber and gas feed'cham- .ber.. Fig. 3ris a transverse seotionof'. the gas feed chamber. Fig. 4 is a cross-section 'of the radially and laterally movableflpis- 1. tons. Fig. 5 is a broken sectional view, illustrating the manner of holding the pack-- ing'rings against the rotor or revolving piston. Fig. 6 is a detail view of the rotor packing devices.

Similar characters of reference are used to indicate the same parts throughout the severalviews.

The engine cylinder is made up of members 1 and 2 which may be bolted together,

or these partsmight bemade integral, and

by the side plates 3 and 4 which are bolted to the parts 1 and 2 res ectively. A rotor or piston 5 is eccentrica I mounted in the cylinder on a shaft 6. he side plates 3 and 4 having bearings 7 forthe shaft 6.

The rotor 5 is provided with recesses 8 and 9 in opposite sides thereof diametrically op-- posite each other to receive the ignited gases from the ignition chamber. The rotor may be provided with hollow sgokes 10 and solid 13 in one spoke 10 and similarpistons 14 1e pistons 12 andand 15 in the other spoke 10 constitute the means for closing the space between the periphery of. the rotor 5 and the interior'of I the cylinder during the revolution of the rotor. The shaft 6 will be rigid with the rotor 5 and the shaft 6 has an opening therethrough registering with the openings in the spokes l0 and springs 16. bear agalnst the inner ends of the pistons 12 and 13, and 1.4

and 15 and keep the pistons bearin at their -erythereof. Springs 19 mounted in the parts 1 and 3 and 2 and 4 bear against the After the rotor outer faces of the packing rings 17. and 18 and set screws 20 are used to maintain the tension of the springs 19. The plates 3 and 4 are provided with exhaust ports 21 and are provided openings 22 for escape of air.

The members'12 and 13 and 14 and 15 have inclined surfaces so that these members will move laterally on each other and keep the spaces between these members and the plates 3 and 4 closed against the passage of explosive mixture or gases.

A cylinder 23 is mounted on top of the engine cylinder or main cylinder and divided into a compression'chamber 24 and an ignition chamber 25 and the chamber 25 is connected to the main cylinder by a tubular connection 26.

A port 27 leads from the chamber 25 to the main engine cylinder and this port is intercepted bya revolving valve 28 which has an opening therethrough adapted to register with the port 27 instantly as the explosion takes place. Means are provided for revolving the valve 28 and it is apparent that the port 27 will be opened an closed twice during each revolution of the valve 28.

The valve 28 is provided with a shaft 29 which is journaled in a bearing 30 and a bevel gear) wheel 31 which meshes with a bevel gear'wheel 32. The gear wheel 32 is rigid with a vertical shaft 33 which is journaled in bearings 34 and 35. The shaft 33 is driven by a bevel gear wheel 36 which is v ri id with theshaft 6 and by the bevel gear w eel 27 which meshes with wheel 36.

The valve 28 will thus be positively driven. On the other side of the engine cylinder from wheel 36 a fly wheel 37 is mounted on the shaft 6 and a cam groove 38 is formed in the side of the wheel 37; A push rod 39 is mounted in a bearing 40 which is formed 38 in the fly wheel 37. By the means thus,

described the push rod 39 will be raised and lowered twice during each revolution of the fly wheel 37. A piston 43 is movable vertically in the chamber 24 and the stem 44 for piston 43 projects through the cap 45. A'-

lever46 is fulcrumed in a bearing 47 which may be formed on the cap' 25. The lever 46 is pivotall connected to the stem 44 and to the pus rod 39. The lever 46 simply bears on to of the push rod 39 and on the stem 44. T e cap 45' has an opening 48 for the stem 44. The piston 43 compresses air in the chamber 24. Rods 49 run throu h openings 50 in cap 45 and down through t e piston 43 and into-lock nuts 51. Springs 52 are mounted-on the rods 49 between the cap 45 and heads on the rods. The rods 49 by means of the springs 52 will automatically raise the piston 43 to the upper limit he chamber 24 is provided in t e cylinder and to be closed immediately upon the release of (pressure in the cylinder. The valve is opene when the piston 43 is pressed down 1) the lever 46 and 39. The cham er 24 is provide nipple 54 in which is mounted a spring actuated valve 55 for closing the opening L- in the chamber 24to the carbureter (not shown) through pipe 56.

The rotor 5 is provided a with packin members 57 at the rear of the recesses 8 and 9 to prevent any possible leaking of the ex plosive mixture backwardly.

A spark plug 61 projects into the chamber 25 and a contact maker is loosely connected to the push rod 39 so that the contact maker will engage the spark plug at regular intervals, or whenever the' push rod 39 is actuated.

What I claim is 1. An internal combustion engine comprising a cylinder having a compression slides radially outward, sai recesses on'opposite sides at the rear of, said .mixture in said chamber, sai

ush rod with a chamber therein provided with intake and exhaust ports, a power transmitting shaft eccentrically mounted in said chamber, a rotor mounted on said shaft for driving the same, beveled piston slides radially mounted in said rotor and adapted to extend out of .the periphery of said rotor, a spring operating throu h said shaftfor rojecting said rotor having piston slides, means for supplying explosive mixture to said recesses and chamber, and

.means for igniting the explosive mixture.

' 2.. An internalcombustion engine comprising :a cylinder having a com ression chamber, a power transm1tt1ng sha t eccentricall mounted in said chamber, a rotor in said c amber for'driving-said shaft, means for supplying explosive mixture to said 1 chamber, piston slides radially mounted in said rotor for controlling the explosivemixture, a balance wheelzrigid with said shaft and'provided with acam groove in one side,

and sparking mechanism operatively connected with said balance wheel and automatically actuated thereby for i 'niting the sparking mechanism 'consistin of a-spark plug pro jecting in said cham er, a push rod having aj lug engagmg-saidgroove, and a contact maker carried loosely on said push rod and adapted to'en age said spark plug lar intervals uring operation.

.3. An internal combustion engine comprising a cylinder having a compression at reguchamber therein and provided with intake and exhaust ports, '-a"power transmitting shaft eccentricall'y mounted in said {chem-'1 her, a rotor mounted on said shaft for driv ing the same, pairs-of. piston slides mounted- 'in"said rotor. and adapted to: bear against the interior of said."chambenffa common resilient element in v-said" rotor bearing against the inner endsof saidfpairs-ofslides,

said rotorhaving recesses inv thefp'eriphery thereof v.at th'e of said pistonslides and iting the explopacking in th'e periphery at the rear of said recesses, and means; for "i sive mixture in said cham 'r'.

In testimon' whereof I setmy hand'this 24th day of arch,-19 19.
